Seasonal style, as we often say here at The Style Guide, narrows down to being prepared before you’ve got to be prepared. Yes, that extends to pieces specifically made for the worst spring weather out there, like one of the best rain jackets, but it goes for your warm-weather tailoring, as well.

And there’s no brand that fits the bill in terms of classic style and even utility than Buck Mason — and yes, that extends to dressier styles in the California-based brand’s clothing line, too.

The Buck Mason Carry-On Jacket first marked the all-American brand’s foray into tailoring, and it’s only gotten better in the years since then. And the latest and greatest iteration is perhaps its most lightweight, dependable and versatile offering yet for when you need to look polished as the thermostat climbs (slowly but surely).

The key with this new edition of the Buck Mason Carry-On Jacket is the use of what the brand calls its “parachute poplin” fabric, which just so happens to be a 5.5oz. cotton poplin that’s also garment-washed for an even softer feel and finish. That fabric should stretch and move naturally on its own while retaining its shape and (ideally) avoiding wrinkles. And the laundry list of features that elevate your new favorite blazer only carries on from there.

The Buck Mason Carry-On Jacket boasts casual, laidback details like patch pockets and a classic two-button design. And washed-out, pleasingly dusty colors like Sand and Tanker Green deliver some spring and summer-minded flair: Either option would work well with the matching Buck Mason Carry-On Suit Trousers or perhaps a pair of expertly faded Buck Mason jeans.

And the Buck Mason Carry-On Jacket should prove a solid fit out of the box, with sizes ranging from S-XXL (refer to the brand’s fit guide for more).

Whether you’re searching for a lightweight, breezy blazer for Casual Friday, a crisp yet comfortable suit for a spring and summer wedding, or a polished blazer you can easily wear for business travel (and beyond), consider the Buck Mason Carry-On Jacket your new must-try spring and summer jacket.
